The numbers of nodes and elements are shown in talbe1 and the FE model is shown in figure 4.
We surmise that the different decolorization behavior of methyl orange using pure and doped ZnO films might originate from the different microstructure changes upon high temperature annealing, i.e., ZnO microcrystalline grain grows at high temperatures while Mn dopants in Zn1−xMnxO films may transit from substitutional to interstitial sites at high temperatures, as hinted from XRD measurements (not shown) and earlier reports [23].

The density of geometrically necessary dislocations (GNDs) decreased with the increase of indenter load and the density of statistically stored dislocations (SSDs) showed a dependence on the grain size of β phase which mainly contributed to the variation of microhardness regardless of indenter load for the Ti-1023 titanium alloy [10].
Cheng and Tunvisut [18,] [19] used dimensional analysis to propose a number of dimensionless universal functions.

Introduction
Windmills have been used for at least 3000 years, mainly for grinding grain or pumping water, while in sailing ships the wind has been an essential source of power for even longer.

At lower temperatures, H2S gas can reduce the surface by reacting with ionosorbed oxygens on WO3 grains when a catalyst exists on the surface.
The coexistence of two oxidation numbers of copper (+2, +1) in the samples may be due to an increase in the degree of oxidation of Cu in Cu2O through the annealing process.

Especially, when forming perforated aluminium sheets in micro scale, only a limited number of studies on their formability have been conducted.
Micro formed materials cause higher scattering of the material properties due to so called size effects like a lower amount of grains compared to macro scale [5].
